Need the factory specs for your wheeled excavator? This 738-page Cnh WX150, WX170, WX200 service manual PDF (OEM #Cre 9-53961GB, including the 200M variant) details every pump, axle, and boom assembly procedure. You get step-by-step teardowns for the Trasmital reduction gears, Carraro front axles, and CAV injection pumps. Open up to find detailed exploded views of the entire upperstructure, complete diagnostic charts for the electronic system, and page after page of torque tables. Verify the rated pressure of the attachment and travel function is hitting 355 to 365 bar, then lock down the engine-to-pump retaining screws at exactly 44 Nm. Your machine is down. Get the right numbers instead of guessing. Grab this bookmarked file, open it on your shop tablet, and start wrenching.

Cnh WX150, WX170, WX200, WX200M Common Problems This Manual Covers
Cnh WX150 hydraulic pump grinding noise after 200 hours, bucket struggles to lift loads
Check the hydraulic pump mounting per page 313: torque the engine/pump retaining screws to 44 Nm and the coupling splined sleeve screws to 100 Nm. Verify rated pressure holds at 355 to 365 bar (450 bar on heavy lift). Grinding at 200 hours usually means a worn coupling or starved suction line; inspect the strainer before condemning the pump.
Manual Section: Upperstructure Hydraulics (Swivel & High Pressure Pumps) p. 313Engine overheating with repeated shutdowns during operation even after recent coolant service
Drain and check the coolant mix per page 25: ethylene-glycol must be at least 50% and not exceed 50% at ambient above minus 36 degrees C. Inspect the radiator cap and core for blockage, verify the water temperature sensor at the cylinder head reads accurately, and fully bleed the cooling circuit before restarting.
Manual Section: Engine Removal & Radiator p. 25Unexpected loss of power steering control while maneuvering the machine on uneven ground
Inspect the steering cylinder tie-rod lock nuts per page 291 and torque to 300 Nm if loose. Check the steering line for external leaks and verify reservoir fluid level. Sluggish or lost assist often traces to a failing steering pump or air ingress; bleed the circuit fully and retest before condemning the pump.
Manual Section: Undercarriage Hydraulics (Cylinders) p. 291Starter motor cranks slowly or won't turn over in cold weather mornings
Run the No-Load starter test described starting page 32. Torque starter motor mounting bolts to 43 Nm and check battery cable connections for corrosion. High current with no rotation points to a seized starter; zero current or low speed in cold weather usually means weak batteries or a bad ground.
Manual Section: Starter Motor Diagnostics p. 32Hydraulic oil temperature climbs high and triggers shutdown warning during heavy digging cycles
Check the hydraulic fan motor section starting page 403. Measure travel motor internal leak flow and confirm it stays under 23 L/min per page 221, since excess leakage generates heat. Verify the oil cooler core isn't clogged and the fan is turning at full speed under load before replacing the temperature sensor.
Manual Section: Upperstructure Hydraulics (Rotary Valve & Fan Motor) p. 403Frequently Asked Questions
How to reset the error codes on CNH WX150, WX170, WX200, WX200M wheeled excavators?
For specific error codes like D005 and D007, which indicate issues with engine water temperature detectors, reversing the connection between temperature sensors (1) and (2) will make the defect disappear from the control screen. p. 11
What are the torque specifications for hydraulic pump mounting bolts on CNH WX150, WX170, WX200, WX200M?
When installing the hydraulic pump, the retaining screws should be tightened to a torque of 44 Nm. This specification is crucial for proper assembly. p. 9
What is the reset procedure for the servo-motor calibration on CNH WX170 and WX200?
To calibrate the servo-motor if it has been removed, refer to section 4002 of the manual. The specific calibration procedure is not detailed in the provided text. p. 11
Where can I find the hydraulic pressure relief valve torque specifications for CNH WX200M?
For the stabilizer/dozer blade control valve section, the secondary relief valve should be tightened to a torque of 90 Nm. This is a specific torque setting for a type of hydraulic pressure relief valve. p. 257
What is the minimum brush length for the starter motor?
The minimum brush length for the starter motor is 8.5 mm. If any brush is found to be shorter than this specification, both brushes must be replaced. p. 32
What format is this Cnh WX150–WX200 Series manual in?
This is a 738-page searchable PDF ready for immediate download. Works on any device, so pull it up on your phone while you're under the hood. No shipping, no waiting.
Can I print specific sections of this Cnh WX150–WX200 Series Service Manual?
